Apparatus and Method for Reducing PAPR using SLM

摘要

Disclosed is an apparatus and method for reducing PAPR using SLM. The disclosed apparatus includes a group setting unit that divides multiple antennas into a plurality of groups and sets the number of phase sequences to be used in each group; A phase selector for selecting one of a plurality of phase sequences set to be used for each group for each group; And a phase application unit that transmits a signal by applying the selected phase sequence to all antennas belonging to each group. According to the disclosed apparatus and method, it is possible to effectively reduce PAPR while using SLM in a multi-antenna environment.
